Author's NotesIs your cell phone signal strength OK where you use it most? Easy to use. No ads


Check how good your cell phone signal strength is at home or at work, upstairs or downstairs.

Is the signal strength low or are you having a lot of cell handovers (handoffs) due to a poor signal; check if you should consider a different cell phone operator, or make your important calls from a different room.

Phone Signal Strength allows you to check cell phone signal quality in detail (signal strength, handovers, radio type changes) over time and get network cell information.

Monitor signal strength
Provides an overview of SIM, network and signal strength (up to 1 minute). The signal graph is color-coded to represent the signal level (green, yellow, red). Cell handovers (handoffs) are shown with vertical orange bars. Cell radio technology changes (e.g. LTE 4G to UMTS 3G) are shown with blue vertical bars.

Please note that not all phones correctly report signal strength. If you have a problem with Phone Signal Strength, please report it as a bug and I will investigate. Thanks.
